FOUNTAIN STENCIL AND MARKING BRUSH.

Application filed April 4,

To all whom it may concern:

Be it known that I, WALT C. MARSH, a

citizen of the United States, residing at Belleville, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in'Fountain Stenoil and Marking Brushes, of, which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improved fountain stencil and marking brushes and has for its object to provide a brush having a handle-reservoir, with a finger-operated mechanism interposed between the brush and handle-reservoir, the brush and reservoir being connected by a single valve-containing member having a conoidal inlet from the reservoir and a conoidal outlet to the brush, and a valve seated between said inlet and outlet.

In the drawings Fig. l is a vertical mid-sectional view of a device embodying my invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is an enlarged vertical mid-seciignal view of the valve-containing mem- In the drawings the reservoir 4 is shown, its open end being screw-threaded as indicated by 5 to seat upon the threaded mouth 6 of the valve-containing or intermediate member 7. In said member 7 I provide a conoidal ink-inlet 8 and a conoidal ink-outlet 9 connected by the bore 10. Transversely to the bore 10 is the valve-chamber '11 in which the valve 12 is slid-ably mounted. The valve, 12 has an annular groove 13 about its periphery around and through which groove 13 ink will flow when the valve 12 is in the inner and depressed position shown in Fig. 3.

The mouth of the chamber 11 is closed by 1921. Serial no. 458,360.

outer or closed position. By thrusting the cap 18 inwardly the teeth 1717 will engage with the groove 16 so that the rotation of the cap-l8 will serve to unscrew and remove the screw-plug 15.

The valve-seating or intermediate member 7 has an annular groove 21 surmounting the annular shoulder 22 so that when the reservoir 4 is seated in place (see Fig. 1) the groove 20 will serve to catch and hold any leakage that may exist.

The base of the intermediate member 7 has the. internally screw-threaded mouth 23 to receive and hold the brush 21, whose base is provided with a central feed-tube 25 to receive ink from the outlet 9. p

The cap 18 and the integral stem 19 and valve 12 are freely rotatable at all times except when the teeth 1717 are engaged with groove 16, when the cap 18 serves as a screwdriver to unscrew the plug 15 from its seat, or again return said plug 15 to its seated position.

The described construction provides for an accurately controlled flow of ink, and the ready separation and cleansing or renewal of the parts.

Structural changes in the several parts of the device may be made without departing from my invention in the new and useful particulars above described and hereinafter claimed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a device of the class described, a valveholdingmember having an ink-inlet, an inkoutlet and a bore connecting said ink-inlet and said ink-outlet, wit-h a valve-chamber extending through said bore; a screw-plug mounted in the mouth of said valve-chamher and having a groove upon its outer face; a valve seated in said valve-chamber and having a stem extending through said screwplug and a cap fixed to the outer end of said stem, said cap having teeth arranged to engage with the groove of said screw-plug.

In testimony whereof I hereunto affix my signature.
